Tutorial quote: Now that the Xen 3.0 packages have made it to Debians unstable distribution installation has become much more straightforward. Here we'll take a look at installing and getting started with it upon a generic unstable machine.

Tutorial quote: This guide explains how you can do a live migration of an LVM-based virtual machine (domU) from one Xen host to the other. I will use iSCSI to provide shared storage for the virtual machines in this tutorial. Both Xen hosts and the iSCSI target are running on Debian Lenny in this article.

Tutorial quote: This tutorial provides step-by-step instructions on how to install Xen on a Debian Lenny (5.0) system (AMD64). Xen lets you create guest operating systems (*nix operating systems like Linux and FreeBSD), so called "virtual machines" or domUs, under a host operating system (dom0). Using Xen you can separate your applications into different virtual machines that are totally independent from each other (e.g. a virtual machine for a mail server, a virtual machine for a high-traffic web site, another virtual machine that serves your customers' web sites, a virtual machine for DNS, etc.), but still use the same hardware. This saves money, and what is even more important, it's more secure. If the virtual machine of your DNS server gets hacked, it has no effect on your other virtual machines. Plus, you can move virtual machines from one Xen server to the next one.

Tutorial quote: Ganeti is a cluster virtualization management system based on Xen. In this tutorial I will explain how to create one virtual Xen machine (called an instance) on a cluster of two physical nodes, and how to manage and failover this instance between the two physical nodes.

Tutorial quote: This article describes how to prepare a CentOS 4.4 server for OpenVZ virtual machines. With OpenVZ you can create multiple Virtual Private Servers (VPS) on the same hardware, similar to Xen and the Linux Vserver project. OpenVZ is the open-source branch of Virtuozzo, a commercial virtualization solution used by many providers that offer virtual servers.

Tutorial quote: This tutorial shows how you can enable networking in Xen guests (domU) on Hetzner's new EQ servers. With the new EQ servers, you can get up to three additional IPs that are in the same subnet as the server's main IP. The problem is that these additional IPs are bound to the MAC address of the host system (dom0) - Hetzner's routers will dump IP packets if they come from an unknown MAC address. This means we cannot use Xen's bridged mode, but must switch to Xen's routed mode where the host system (dom0) acts as the gateway for the guests.

Tutorial quote: This tutorial shows how to install and configure BASE (Basic Analysis and Security Engine) and the Snort intrusion detection system (IDS) on a Debian Sarge system. BASE provides a web front-end to query and analyze the alerts coming from a Snort IDS system. With BASE you can perform analysis of intrusions that Snort has detected on your network.

Scenario: A linux server running Debian Sarge 3.1 setup according to Falko's - The Perfect Setup - Debian Sarge (3.1).
Let's assume we have one working website (www.example.com) and that the document root is: /var/www/www.example.com/web
The IP of the server is 192.168.0.5 and it's using eth0 as network interface name.

Tutorial quote: This is a detailed description about the steps to be taken to setup a SUSE 9.2 based server that offers all services needed by ISPs and hosters (web server (SSL-capable), mail server (with SMTP-AUTH and TLS!), DNS server, FTP server, MySQL server, POP3/IMAP, Quota, Firewall, etc.). In addition to that I will show how to use Debian's package manager apt on an rpm-based system because it takes care of package dependencies automagically which can save a lot of trouble.
